IMPROVEMENT IN AUTOMATIC CLOCK ATTACHMENTS FOR OPERATING GAS-BURNERS.

Specification forming part of Letters Patent No. 218,0] 5, dated July29, 1879; application filed June 3, 1879.

To all whom it may concern.-

Be it known that I, SIMON GOLDSMITH, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Automatic Clock Attachments for Operating Self-Lightin g and Self-EX-tin guishin g Gas-BurnerAttachments, of which the following is aspecification.

Figure 1 is a front view of my attachment, shown as applied to aclock-work.' Fig. 2 is a detail view of the drum, ratchet, crank, andconnectingrod. Fig. 3 is a detail view of the cams, bent levers, and thesprings that operate the hammers. Fig. 4 is a detail view of the leversand the springs that hold, release, and stop the ratchet.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved attachment forclocks, to be connected with a self-lighting and self-extinguishingattachment for gas-burners, which shall be so constructed that the gaswill be lighted and extinguished automatically at fixed times, so longas the clock continues to run, so that the only attention required willbe to wind up the clock at the proper time.

The invention consists in the combination of the two gear-wheels, thetwo hands, the two dial-plates, the two cams, the two bent levers,provided with the hammer-heads and the springs, the two levers havingtheir inner ends overlapped and connected together and held down by aspring, the ratchet-wheel, drum, and crank, the cord and weight orequivalent spring, and the connecting-rod, with each other and with thehour-wheel of a clock-work, for operating a self-lighting andself-extinguishing attachment for a gas-burner, as hereinafter fullydescribed.

A represents an ordinary clock-work, and may be a day-clock, an eightdayclock, or a clock that will run for a longer time. To the frame of theclock-work 'A are pivoted two wheels, B, the teeth of which mesh intothe teeth of the hour-wheel of the said clock-work A, or into the teethof a wheel rigidly con-- nected with the said hour-wheel. The wheels Bare made with twice as many teeth as the hour-wheel or the wheel withwhich they gear, so that they will make one revolution in twentyfourhours. To the outer ends of the journals of the gear-wheels B areattached hands 0, which point to division-marks upon the dialplates'D;The dial-plates D are formed upon the outer ends of hubs of s uch alength as to fit in between the hands 0 and the wheels B. Aspring-washer, d, is interposed between the wheels B and the inner endsof the hubs of the dial-plates D, so that the said wheels will carry thesaid dial-plates with them in their revolution.

This construction allows the dial-plates D to be adjusted to set them sothat the gas may be lighted and extinguished at any desired time.

To the hubs of the dial-plates D are attached cams E, which, at eachrevolution of the said diaLplates, strike against and push back the armsof the bent levers F, which are pivoted at their angles to the frame ofthe clockwork A, and to the ends of their other arms are attachedhammer-heads G. The end of the upper arm of one of the bent levers F isbent over into U form, as shown in full lines in'Fig. 3 and in dottedlines in Fig. 1 so that both the hammers G may be raised by the actionof the cams E upon the upper arms of the bent levers F. As the cams Epass from the upper arms of the bent levers F the hammers G drop bytheir own weight, assisted by the action of the springs H, the outerends of which are attached to the lower arms of the bent levers F, andtheir inner ends are attached to the frame of the clock-work A. As thehammers G descend they strike upon the flattened upper sides of theouter ends of the levers I and force the said outer ends downward. Thelevers I are pivoted at a little distance from their inner ends to theframe of the clockwork A, or to supports attached to the said frame orto the clock-case. The inner ends of the levers 1 overlap each other,and the upper lever has a short slot formed through it to receive a pinattached to the lower lever, which pin has a key passed through or a nutscrewed upon its upper end, so that the movement of either lever maymove both. The lower inner end of the levers I is bent downward toengage with the ratchet-wheel J, attached to or formed upon the end ofthe drum K.

The ratchet-wheel J is made with two teeth,

at the distance of a semi-circumference from each other, as shown infull lines in Fig. 4 and in dotted lines in Fig. 1. The ratchetwheel Jand drum K are placed upon and attached to the shaft of the crank L,which revolves in bearings in supports attached to the frame of theclock-work A or to the clock-case. To the drum K is attached the end ofa cord, M, which is wound around it, and to the other end of which isattached a weight, N, so that when the lower inner ends of the levers lare raised by the deseentot either of the hammers G, and thus releasingthe ratchet-wln-el J, the weight N may turn the drum K, ratchet-wheel J,and crank L. The lower inner ends of the levers I are drawn down andheld against the face of the ratchet-wheel J by a spring, 0, so that thesaid drum, ratchet-wheel, and crank can make but halt a revolution atany one time.

The arm of the crank L passes through a hole in the lower end of theconnecting-rod I, where it is secured in place by an arm of the U-shapedpin Q, which passes through a hole in the said end ot the connecting-rodI, and enters a ring'groove in the arm of the crank L. The pin Q is heldin place by a spring. R, 4

attached to it and to the rod l, and its other arm passes through a holein the said rod 1, and projects so that the said pin can be readilypushed back to release the rod 1 and allow it to be detached from thecrank L. The detachment ot' the lower end of the rod 1 from the crank Lallows the said crank to be turned to wind up the cord M and weight Nwithout constantly lighting and extinguishing the gas.

The upper end of the connecting-rod I is designed to be connected withthe self-lighting and self-extinguishing attachment of a gasburner, sothat its movement in one direction may light the gas, and its movementin the other direction may extinguish the light.

The cord and weight M N, that rotate the drum, ratchetwheel, and crank KJ L, may be replaced by an equivalent coiled spring, if desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of the gear-wheels B, the hands (3,the dial-plates D, the cams E, the bent levers I, provided with thehammerheads (t and the springs H, the levers I, having their inner endsoverlapped and connected together and held down by a spring, 0, theratchet-wheel, drum, and crank J K L, the cord and weight M N orequivalent spring, and the eonneetingrod l, with each other and with thehorn-wheel of a clock-work, A, for operating a self-lighting andself-extinguishing attachment for agas-burner, substantially as hereinshown and described.
